  • the upper housing member 22 includes a flat cover portion 96, a depending integral front wall 98, and a rear frame 100, which is secured to the cover portion 96 by welding or other suitable means.
  • the rear wall 98 is provided with slots 102 for ventilating purposes, and is also provided with slots 104 which engage with the projections 50 on the lower housing portion 24 for securing the portions 22 and 24 together.
  • End walls 106 on the front wall 98 are bent ninety degrees from the wall 98 and overlie the end elements 34 and 36 of the walls 28 and 30 of the lower housing portion 24 when the portions 22 and 24 are in assembled relationship.
  • the side edges of the flat cover portion 96 are turned downwardly to form flanges 108 which overlie upper edge elements 46 and 48 when the upper and lower housing portions 22 and 24 are in assembled relationship.
  • Two slots 110 are formed near the rear edge of the cover portion 96 and are positioned to receive upper hook portions of latches 42 and 44.
  • the latches 42 and 44 are of a toggle type of construction, so that when the hook portions of these latches are engaged in the slots 110 and the latches 42 and 44 are moved downwardly by toggle action, the upper housing portion 22 is latched securely to the lower housing portion 24.
  • a tab 111 which extends from the rear edge of the cover portion 96, includes an integral stiffened portion 113, and may be readily grasped at the same time that the tab 41 on the lower housing members 24 is grasped, in order to separate the upper and lower housing members.
  • a large central slot 112 is also provided in the cover portion 96 and permits engagement by an external electrical connector with a vertically positioned circuit board which is located within the housing 20, as will subsequently be disclosed in greater detail.
  • a vertical circuit board frame 114 Secured to the underside of the cover portion 96, to the rear wall 98, and to the frame 100 is a vertical circuit board frame 114 which includes an upper element 116 and a lower element 118.
  • the upper element 116 may be secured to the lower surface of the cover portion 96 by welding, for example, and may be secured to the rear wall 98 and to the frame 100 by tabs 120 and 122, respectively, also by welding.
  • the lower element 118 may be secured to the rear wall 98 and to the frame 100 by tabs 124 and 126, respectively, also by welding.
  • the frame 114 is provided to hold a bus circuit board 128 in a central vertical position within the housing 20 so that connectors 130, 132 on the bottom edge of said board will engage the slots 134, 136 of the receptacles 78, 80 on the board 52 when the upper and lower housing portions 22, 24 are in assembled relationship.
  • Apertures 138 in the frame elements 116 and 118 are positioned to register with apertures 140 in the circuit board 128 when said board is properly positioned, and resilient connectors 142 may then be used to secure the board 128 in place on the frame 114.
  • the bus board 128 serves a busing function in providing communication between a plurality of additional circuit boards, which are plugged into the board 128, and the processor board 52, into which the bus board 128 is plugged by the connectors 130, 132 and the receptacles 78, 80, as previously described.
  • a plurality of receptacles such as the receptacles 144, 146, 148, 150 and 152 (see Fig. 5), are secured to the board 128 in a horizontal orientation, so that additional circuit boards, such as the boards 154, 156, 158, 160 and 162, when plugged into the receptacles, are located in horizontal planes, parallel to the plane of the processor board 52, within the housing 20.
  • the boards 154 to 162 are mounted on both sides of the bus board 128 and that the electrical components mounted on the boards, such as the components 164 to 172, are mounted on opposite sides of adjacent boards. Both of these arrangements tend to maximize the number of boards which can be placed horizontally in the space between the processor board 52 and the cover portion 96.
  • the boards 154 to 162 can be of greater width, in their dimension extending away from the board 128, than they could be if they were mounted vertically and plugged directly into the processor board 52. Looking at the arrangement another way, it permits the upper and lower surfaces of the housing 20 to be closer together in a vertical dimension for a given width of boards 154 to 162 than would be the case if the boards were mounted vertically. This enables standard sizes of boards used in personal computers, such as the IBM PC-­ AT, for example, to be employed in a housing which is smaller in its vertical dimension than would normally be possible.
  • the receptacles 144, 148 and 152 on one side of the bus board 128 are set back from the front vertical edge of the board 128 a lesser distance than the receptacles 146 and 150 on the other side of the bus board 128. This is to permit ground plates associated with the boards to overlap in engaging a central ground connection 174 which is mounted on the frame 100.
  • the ground connection 174 comprises a pair of U-shaped elements 176 and 178 which are secured together.
  • a ground plate 180 is electrically connected to the circuit board 144 and has an angled end portion 202 which is connected to the frame 100 by suitable means, such as screws 182.
  • Apertures in the ground plate 180 are surrounded by connectors 184 and 186 which may be coupled to the shielding of external circuitry.
  • Connectors (not shown), electrically connected to the receptacle 144, extend through the apertures in the ground plate 180 for connection to external electrical conductors.
  • the free end of the ground plate 180 electrically engages an internal surface of the U-­shaped element 178.
  • a ground plate 188 is connected to the receptacle 146.
  • An angled end portion 204 of the plate 188 is connected by screws 200 to the frame 100.
  • the free end of the ground plate 188 electrically engages the outer surface of the U-shaped element 176. It will be seen that providing a structure in which the free ends of the ground plates 180 and 188, which are associated with the receptacles 144 and 146, overlap enhances the compactness of the housing 20.
